vskill

The package manager for AI skills.
Scan. Verify. Install. Across 49 agent platforms.

npx vskill install remotion-best-practices

The Problem

36.82% of AI skills have security flaws (Snyk ToxicSkills).

When you install a skill today, you're trusting blindly:

• No scanning — malicious prompts execute with full system access
• No versioning — silent updates can inject anything, anytime
• No deduplication — the same skill lives in 3 repos, all diverging
• No blocklist — known-bad skills install just fine

vskill fixes all of this.

How It Works

  ┌──────────┐     ┌──────────┐     ┌──────────┐     ┌──────────┐
  │  Source   │────>│   Scan   │────>│  Verify  │────>│ Install  │
  │          │     │          │     │          │     │          │
  │ GitHub   │     │ 38 rules │     │ LLM      │     │ Pin SHA  │
  │ Registry │     │ Blocklist│     │ analysis │     │ Lock ver │
  │ Local    │     │ Patterns │     │ Intent   │     │ Symlink  │
  └──────────┘     └──────────┘     └──────────┘     └──────────┘

Every install goes through the security pipeline. No exceptions. No --skip-scan.

Quick Start

# Install from any GitHub repo
npx vskill install remotion-dev/skills/remotion-best-practices

# Browse a repo and pick interactively
npx vskill install remotion-dev/skills

# Install a plugin (Claude Code)
npx vskill install --repo anton-abyzov/vskill --plugin mobile

Or install globally: npm install -g vskill

Getting E401 errors? If your project has a .npmrc pointing to a private registry (e.g. AWS CodeArtifact, GitHub Packages), npx may fail with npm error code E401. Fix it by overriding the registry:

npx --registry https://registry.npmjs.org vskill install <skill>

Or install globally once to avoid this entirely: npm i -g vskill --registry https://registry.npmjs.org

Three-Tier Verification

Tier	How	Trust Level
Scanned	38 deterministic pattern checks against known attack vectors	Baseline
Verified	Pattern scan + LLM-based intent analysis for subtle threats	Recommended
Certified	Full manual security review by the vskill team	Highest

Every install is at minimum Scanned. The vskill.lock file tracks the SHA-256 hash, scan date, and tier for every installed skill. Running vskill update diffs against the locked version and re-scans before applying.
